CELLAR-DOOR.

Application filed June 6, 1916.

t State of South Dakota, have invented new and useful Improvements in Cellar-Doors, of which the following is a specification.

This invention relates to cellar doors and it consists in the novel features hereinafter An object of the invention is to provide a door structure of simple arrangement adapted to be easily and quickly operated for the purpose of removing a hood from over the door opening in order that a passageway may be etlected through the same, the parts of the device being so arranged that the hood may be readily closed over the said opening thus protecting the opening and preventing persons from crawling through the same.

WVith the above object in view the structure includes a casing adapted to be positioned over the opening and in which a hood is pivotally mounted. A lever mechanism is mounted upon the casing and operatively connected with the hood whereby the swinging of the lever effects the movement of the hood in the casing. The parts which connect the lever with the hood are so arranged that the same or a similar movement of the lever moves the hood from a closed to an open position and vice versa.

In the accompanying drawings Figure 1 is a side elevation of the door structure.

Fig. 2 is a longitudinal sectional view of the same.

Fig. 3 is a plan view showing concealed parts dotted in.

The other figures are detailed views of the features of the invention.

The door structure includes a casing 1 which is adapted to be positioned over the opening in a. floor in the usual manner. The

casing 1 is provided at one'end with an opening at the edges of which are positioned curved or arcuate guide flanges 2. A hood 3 is pivotally mounted in the casing 1 and the said hood is sector shaped in side elevation. The opposite side portions of the said hood are pivotally secured to the sides of the said casing by means of pivot pins 4: attached to the casing and received in lugs or ears 5 mounted at the sides of the said hood. A weight 6 is mounted at the upper Specification of Letters Patent.

intermediate portion of the said hood. When the hood 3 is in a closed position in the casing 1 the weight 6 is positioned just to one side of a vertical line passing through the pins A and when the said hood is in an open position in the casing the said weight is positioned at the opposite side of the said line but at a considerable distance from the same.

A lever 7 is fulcrumed at one end to the casing 1 at a point below the top thereof and just above one side. The said lever extends transversely under the top of the casing and projects beyond the opposite side thereof through an opening which is provided in the last mentioned side. A lever 8 is fulcrumed to the casing 1 beyond the outer surface of one side thereof and the free end portion 'of the said lever 8 passes hrough a guide 9 mounted at the same side of the casing 1. An arm 10 is carried by the lever 8 and the upper end of the said arm is pivotally connected with the free end of the lever 7 at a point beyond the outer surface of the side of the casing 1. A brace bar 11 is interposed between the lever 8 and the arm 10 and serves to hold the said parts in rigid relation with respect to each other. The upper end portion of the arm 10 is movably mounted in a guide 12 mounted at the side of the casing 1.

A bar 13 is pivotally mounted on the easing 1 at the same side thereof as that side at which the lever 7 is pivotally mounted and a link 14 operatively connects the free end portion of the bar 13 with the free end portion of the lever 7. The bar 13 and the link 14 lie under the top of the casing 1. A journaled pulley 15 is carried at the free end of the bar 13. A spring 16 is connected at one end with the free end portion of the bar 13 and at its other end with the back of the casing 1 and is under tension with a tendency to normally hold the free end of the said bar toward the back wall of the said casing.

A rod 17 is connected at its ends with the sides of the casing 1 at a point below the top thereof and in the vicinity of the back wall of the said casing. A pulley 18 is journaled upon the said rod and the said rod is provided at a point between its ends with an opening 19. A bracket 20 is attached to the back wall of the casing 1 and carries at its upper end a pulley 21. A cable 22 is attached at one end to the inner portion of the hood 3 and from the said hood extends over the pulley 21 thence around the pulley 18 and then around the pulley 15] From the pulley 15 the said cable is threaded through the opening 19 in the rod 17 and the said cable carries at its inner or lower end. a weight 23 which may be in the form of a hand grip.

In View of the fact that the spring 16 is under tension and is connected with the bar 13 the free end portions of the said bar 13 and the lever 7 are normally maintained toward the back wall of the casing 1 and inasmuch as the lever S is connected with the lever 7 by means of the arm 10 the free end portion of the lever S is normally maintained in an elevated position in the guide 9.

Assuming that the hood 3 is in a closed position in the casing 1 an operator at the exterior of the said casing depresses the free end of the lever 8 whereby the bar 13 is swung by the parts which operatively connect the said bar with the said leverand thus the spring 16 is stretched. During the swinging movement of the bar 13 the cable 22 is moved longitudinally which first brings the weight in contact with the rod 17 and then further movement of the said cable swings the hood 8 in the casing 1 whereby the weight (3 is carried. across the vertical line passing through the centers of the pins l. In view of the fact that the said Weight is transferred from one side to the other side of the said line the hood 3 will then swing to an open position in the casing 1. The same movement on the part of the hood is effected by one who may be below the casing by exerting a pull on the cable 22, using the weight 23 'as a handle.

Assuming that the hood is in an open position in the casing 1 and it is desired to close the same the lever 8 is swung as hereinbefore described whereby the cable 22 is moved longitudinally and the weight 6 carried by the hood 3 is moved from one side of a vertical line passing through the centers of the pins 4: to the opposite side and consequently the said hood is swung from a closed to an open position in the casing l. The same closing movement on the part of the hood may be effected by one who is below the casing by using the weight 28 as a handle.

From the foregoing description taken in Copies of this patent may be obtained for conjunction with the accompanying drawing it will be seen that a cellar door opening closure of simple and durable structure is provided and that the parts may be easily and quickly manipulated to effect the opening or closing movement of the hood to afford access through the door opening or to close the same.

Having described the invention what is claimed 1. A door structure comprising a casing, a hood pivotally mounted therein, said hood being weighted at one end, a lever fulcrumed upon the casing and means operatively connecting the lever with the hood whereby said lever when swung is adapted to move the weighted end portion of the hood from a position at one side of a vertical line passing through the pivot of the hood to the opposite side of the said line.

2. A door structure comprising a casing, a hood pivotally mounted in the casing and being weighted at one end, a lever fulcrumed upon the casing and disposed transversely thereof, a lever fulcrumed at the exterior of the casing and operatively connected with the first mentioned lever, a bar pivoted upon the casing and operatively connected with the first mentioned lever, and a cable connected at one end with the hood and adapted to engage the casing at its other end, the intermediate portion of the said cable engaging the said bar.

3. A door structure comprising a casing, a hood pivotally mounted therein and weighted at one end portion, a lever fulcrumed upon the casing and disposed transversely thereof, a lever fulerumed at the exterior of the casing and op'eratively connected with the first mentioned lever, a bar pivoted to the casing and operatively connected with the first mentioned lever, a rod disposed under the casing and having an opening, pulleys journaled under the casing, a cable connected at one end with the hood and trained around the said pulleys and engaging the said bar, said cable passing through the opening in the rod and a weighted handle grip carried by the cable and adapted to engage the rod when the cable is moved longitudinally.

In testimony whereof I aflix my signature.
